SOVJING DEVICE ATTACHMENT FOR PGTATO DIGGERS.

Application filed August 12, 192. Serial No. 212,510.

for digging potatoes out of the ground, and

simultaneously planting into the dug'up ground, small seeds such as corn, grain,cetc., covered by ground simultaneously dispensed.

Another object of my invention is the pro-- vision. of a combination digging and plant-1 ing machine equipped with means for transporting the dug up potatoes, etc., towards the rear of the machine. I p I A further object of myinvention is the provision of a combination potato digging and seed planting machine in which the seed slantin ho Joer is )rovided with a means 1 for regulatmg the width of the seed dispensing openings and with means "for stirring up these seeds which are driven from a moving part'of the machine.

A still further. object of my invention r the provision of a machine of this type saving time and labor and allowing the cutting out of the operation of the digging and planting operations if this is desired for moving the machine from one place of operation to another.

These and other objects and advantages of my invention will become more fully known as the description thereof proceeds, and will then be more specifically defined in the appended claims. c

In the accompanying drawings, forming a material part of this disclosure:

Figure 1isa top plan view of acone bined potato digging and seed planting machine constructed according to my invention. Figure 2is' a side elevation thereof. Figure 3-is a sectional end view of a seed distributor, or box used with my machine, the section being taken on line 3+3 of F igure 1. Figure 4l-is a bottom plan view of the seed distributor or box.

Figure 5is a side View of said seed distributor or box. a

As illustrated on the drawing, the machine comprises the customary frame on wheels 11, 12, to the front part of'which the usual beam 13 for attachment ofthe draft animals is attached. I The frame 10 carries at a certain distance above the same a seat 14 for the operator,

'ing an endwise arranged digging and below the same a potato digger 15, havand which is pivotally attached intermediate its ends, as at 17, to the frame. Below its pivot point a curved arm' 18 is pivctally secured atits lower end, as at 19, to the side of digger while its upper end has pivoted thereto one end of a link 20 pivoted at its other end to a hand lever 21, the lower end of which is movably secured to a bracket 22 having also attached thereto a toothed segment 23 while the usual spring detent 2 f engages the teeth of the segment for maintaining the lever at predetermined set positions. To the pivot point of the substantially vertical lever 21 is also pivoted a point, 16,

substantially horizontal lever 25 serving a purpose hereinafter more fully to be described.

Cross-shafts 26, 27 on the digger frame 15 carry sprocket wheels 28, 29 respectively over which an endlessconveyor 30 is guided which'is operated from a motor 31 by means of a chain 82 guided over sprocket wheels on shaft 27 and on the motor shaft. The motor is supported by 'asuitable frame 33 on the machine frame. 1

At the front part of the machine frame 10 a'seed distributor box 84: is supported transversely thereto in suitable brackets 35 and the box 34 is open at its top while the side walls thereof are of inwardly converging relation, the point of these niergence being of rounded contour, as at 36,,and formed with seed discharge openings, the size of which. can, be regulated as will hereinafter be more fully described.

Suitably journaledthrough the box 3 directly above the bottom thereof is a rotary shaft 37 which carries a plurality of juxtaposed and spaced agitator wheels 38, having recesses 39 in the periphery for the reception of the seeds. v

The shaft 37 carries a coupling member 40 adaptedto be engaged by a coupling member 41 on a stub shaft 42 journaled in the machine frame which carries a sprocket wheel 43 over which a. chain 44 is guided which is also guided over a sprocket wheel on the rear axle 51 carrying the wheels 11.

The coupling is operated to engage its members 40, 41 or to separate the same by means of the rod 25.

The means for enlarging or for decreasing the size of the seed distributing openings comprise the member 52, of a form best illus- 'trated in Figure 4, each of which is pivoted at one end to a slide bar 58, and at its other end to a slide bar 54, guided in suitable guides 55, at the bottom of box 34, and bar 58 carries a pin 56 engaged between the torked'ends of an operating lever 57, rotatably attached intermediate its ends to a post 58 while its outer end is engaged between the forked lower end of a vertical operating lever 59 pivotally attached intermediate its ends to the side wall of the box A scale (30 is suitably arranged to indicate the size of seeds to be planted for suitably regulating the dispensing openings.

It will be clear that box 8% is filled partly with the seeds which are mixed with asuitable supply of soil.

My device operates as follows:-

While the machine is drawn forward by means of the draft animals, the motor is started to operate the conveyor for the reception of the potatoes dug up by tl'ie'digger 16, which then are deposited in rear of the machine, as at 61 to be collected in suitable receptacles while the still uncovered seeds other than potatoes are covered with the loose ground or soil remaining from the digging operation.

When it is desired to plant the seeds, coupling members 40, 41 are engaged by means of the proper operation of levers 21, 25 and the agitators will dispense the seeds and soil from box 34, after the width of the dispensing openings has been properly regulated by means of lever 59.

the

It is to be understood that I have disclosed a preferred form of my invention one example only, and that such changes may be made therein as come within the scope of the appended claims without deviation from my invention.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is In a seed distributor for )otato )la-nters a seed receiving and distributing box having an open bottom, a rotary shaft journalled in the end walls of said box above said open bottom, a plurality of uxtaposed and spaced agitator wheels on wheels having recesses in its periphery for the reception of the seeds, and members of a peculiar shape for enlarging and decreasing the size of the seed distributing openings, slide bars to which the ends of each of said members are secured, guides on the bottom of said box for said sliding bars, a pin on one of said bars, and a lever having a forked end adapted to engage said pin pivoted in termediate its ends to a post on the bottom of said box, and an operating lever pivotally attached intermediate its ends to the side walls of said box, and having a forked lowen JOHN B. nonosr tr.
